Specification of Letters Patent.

'Eatented may 29, 1906.

Application filed September 5,1905. Serial No. 277,078.

To n] l whom it may concern: v

Be it known that I, Gos'rav Mas, factory manager, a subject of the German Emperor, residing at Lichtent-aler Alla, Baden, Grand Duchy of Baden, in the Empire of Germany, have inventedcertain new and useful Improvements in Lctter i iles and. the Like, of which the following is a specification.

The present invention has for its object a top bar for files for letters and the like, which is broadly characterized by the fact that the lateral edges of this bar are turned over upwardly throughout its entire length, so as to form slots or grooves in. which one or more slides are guided. This formation is especially applicable to cases in slides are used, because the outer positions of the slides may be limited in a very simple manner by providing the grooves with simple indentations at the desired places, and thereby limiting the path of the slides. A.

particularly advantageous construction is one in which the interval between these limiting indentations and the PQI'EOI'ZMLIOHS through which the binding-bands pass in the ar is such that in their extreme outer position: the

slides uncover the openings, so that the hinding-bands may be turned over either in- Wardly or outwardly, as desired; Although the formation of the grooves strengthens the bar, if desired, it may still further strengthened by providing it with a middle 1 longitudinal rib.

Figure 1 of the accompanying drawings shows this novei top bar in perspective at the moment at which it is being passed upon the binding strips a a, which in the present case are assumed to be fixed upon the fold f of a filcy. They may, however, be fixed upon the cover of the file itself. Fig. 2 shows the top bar with the slides'e e pushed outwar with the binding-strips turned down outward. Fig. 3 shows the top bar in side elevation. Fig. 4 represents the slides a c in their end position with the binding-strips turned down inward. Fig. 5ishows theinanner in which the slides retain bent strips. the bar on the line A B of Fig. 2 die rib is formed, and Fig. 7 is a similar section with strengthening-ribs.

In the top bar represented in the drawings its outer edges are bent over upwardly n such. a manner which the two slides e e are able to slide to and fro. Their extreme outer position is dewhich two the inwardly Fig. 6 is a L'IOSSSCUOI1 through when no nndthat they form grooves 131.

sition either the Whole of the openings g or a ortion of them are uncovered, so that the I l l bindingstrips may be inserted, as shown in Fig.4. r

if it is desired to turn the binding-strips down outwardly, in the are arranged in the middle, as shown in Fig. i 1. If, on the contrary, it is desired to turn the binders down inwardly, the slides are l first an anged in the positionshown in Fig. i. l The advantages of the invention reside in l the iaciiehah owing to the turning over of its i edges the top bar of the file considerably lstreng'thcned throughout its entire length. i Top bars for files of theusual kind-that is to say, those in wh idh 'no such stiffening is pro.- 'v'idcd upon their outer cnds present the defect, if they are of any considerable length, 5 of readily bending at the ends, so that they hold down the edge oi the letters or the like imperfectly. It is, however, of great importance that the edge should be held down, the middlportion of the letters being sel cured by the binders, while the outer ends del pend upon the bar for their retention. This one a San further increased if the 'baris made of the cross-section shown in Fig. 7 that is to say, forn'ied with a middle rib 'r. In most cases, l'iowe'ver, a rectilinear crosssection, such as illustrated in Fig. 6, is sufficient. The further advantage is secured that the slides-cannot possibly tear the letter. i beneath them in their displacement. The i indentations in the grooves constitute an exceedingly simple means for limiting the dispiacementof the slides. I i The form of the slides and their length may l vary. as desired. if his desired to limit the i. displacement of the-slides toward the midl indentations. i
